Anglesey covers 720 square km which makes it the largest Welsh island and is also the fifth largest surrounding the UK. Welsh is commonly spoken on the island which reflects the islands long history. The Welsh name for Anglesey is Ynys Mon and the island is known as Mon Mam Cymru or Mother of Wales as the Romans believed the low lying island would be fertile enough to provide food for all of Wales. The oldest settlers were Druids and Anglesey has many ancient megaliths and burial chambers worth a visit. Several Roman and Iron Age sites have been excavated with dwellings and remains visible from every era.
